Astronomers using several ground-based telescopes have spotted the most distant cosmic jet discovered so far. Its source is PSO J172.3556+18.7734, a radio-loud...
Recent measurements of the expansion rate of the Universe have plunged the standard model of cosmology, the ΛCDM model, into a crisis. In a new paper...
Theoretical physicists from Italy, Spain and Argentina propose a new mechanism for the creation of supermassive black holes from dark matter.
Galaxy halos...
The majority of supermassive black holes lie dormant and starved of fuel; these hidden giants can be temporarily illuminated when an unlucky star passes...
ALESS 073.1, a star-forming galaxy located 12.5 billion light-years away, has all of the features expected of a much more mature galaxy and has led astronomers...
In a paper to be published in the journal Physics Letters B, a duo of theoretical physicists from the University of Sussex shows that quantum gravity leads...
If ‘stupendously large’ black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful...
Using a deep residual neural network and data from the Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys, astronomers have discovered...
Astronomers using the MeerKAT radio telescope at the South African Radio Astronomy Observatory in Cape Town, South Africa, have discovered two new radio...
The newly-discovered quasar is located approximately 13.03 billion light-years away from Earth. Designated J031343.84-180636.4 (J0313-1806 for short),...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a massive starburst galaxy with a tail of star-forming gas in...
Astronomers using the NASA/ESA Hubble Space Telescope have detected and studied numerous young star clusters in six merging galaxy systems.
Adamo et al....
Whenever two compact objects (black holes or neutron stars) collide elsewhere in the Universe, they create gravitational waves that travel across space,...
In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial...
Astronomers have observed a bright one-sided jet of material ejected at three-quarters the speed of light from the core of the blazar PSO J030947.49+271757.31...
Using the eROSITA X-ray telescope onboard the Spectrum-Roentgen-Gamma (SRG) space observatory and CSIRO’s Australian Square Kilometre Array Pathfinder...
Dark matter proponents theorize that most of the known Universe is actually made of material that doesn’t interact with light, making it invisible and...
GN-z11, a young but moderately massive galaxy located in the constellation of Ursa Major, is estimated to date from when the Universe was only 420 million...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a striking photo of GAL-CLUS-022058-38303, the largest and one of the most complete...
Astronomers using CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) have mapped approximately 3,000,000 galaxies in the observable Universe.
ASKAP...
